摘要：Experiments for single wave packets evolution in deep-water were carried out to study the characteristics of wave breaking. The energy loss by breaking and the local characteristics of the breaking during the evolution were analyzed by Hilbert-Huang transform (HHT). The findings show that the main energy dissipation by wave breaking is the high frequency contents. And the instantaneous frequencies of the first intrinsic mode function for the breaking cases vary greatly around breaking locations.
